## Filename: 	Makefile	(sw/host)
##
## Project:	CMod S6 System on a Chip, ZipCPU demonstration project
##
## Purpose:	Supports the building of the various host (i.e. PC) software
##		that will be used to support the Cmod S6 board.  None of this
##	software will actually run on the board, but it may be used for 
##	communicating with and configuring the board.
